Abstract: The integration of cold atomic sources and electromagnetic field sources in the same device is a major frontier for both fundamental science and advanced technology. In this paper, we discuss the realization of the Bose-Einstein condensate (BEC) on an AtomChip and describe such an experimental configuration realized at LENS. We also concentrate on the realization of a particular integrated matter wave interferometer where coherent coupling between the BECs in different Zeeman states is used to produce a fringe time-population signal at the output. Finally, we discuss the prospects for application of such a device as a multi-path interferometer.
